SPECIFICATION forming part of Letters Patent No. 243,909, dated July 5, 1881.

Application filed May 6, 1881. (No model.)

To all whom it may concern:

Be it known that we, ANTHONY IsKE and ALBERT ISKE, citizens of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Motors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention is an improvement on a motor which is the subject of an application for patent filed on the 8th of February, 1881, and subsequently allowed but not yet patented. In the said prior application we have described a set of tubes turning on a common center and provided at each end, on opposite sides, with a bulb or ball, the air being exhausted from said bulbs and tubes, and the same partly filled with some volatile liquid, so that the application of heat to the bottom of the motor will cause the revolution thereof, as therein described. Further experiment has resulted in showing that sundryimprovements are needed to get the utmost advantage from the means employed. For example, the tubes used in the above motor have their ends necessarilybent so as to enter the bulbs or balls at the side thereof, and in consequence the dischargingbulb passes some distance beyond the center before the bulb atthe upper end of the tube receives its full charge. Again, the heat was applied in said motor chiefly, if not solely, to the bottom of each bulb as it came round in turn,whereasan equal simultaneous application of the heat to all parts of the bulb would obviously produce more immediately the desired effect. It is also found that a considerable degree of heat escapes laterally without renderin g any service when the receptacles at the ends of the tubes have the form of bulbs or round balls.

To remedy these defects we first make the tubes straight, 'and extend them at each end into the bulbs and nearly through the same;

secondly, we employ a vessel or reservoir of hot water or other liquid, into which the bulbs, balls, orreceptacles dip as they revolve; and, thirdly, we make the said receptacles in the form of hollow cylinders or other elongated compartments, instead of bulbs or balls.

In the accompanying drawings, Figurel represents a perspective view of our improved motor, the bulb form of receptacle being employed. Fig. 2 represents a detail view of one of the separate tubes constituting the same. Fig. 3 represents a central longitudinal section of our motor, having the receptacles in the form of elongated chambers united in the form of a wheel or drum. Fig. 4 represents a detached perspective view of the cylindrical receptacles and tubes similarly united in one drum. Fig. 5 represents a detail view of a pair of these cylindrical receptacles or substitutes for bulbs and the tubes connecting the same.

In the foregoing figures similar letters designate corresponding parts.

A designatesthe frame, which affords bearings for the shaft or axis B of our motor. To this shaft the tubes 0 are attached at their middle parts,where each tube is slightlycurved,

so that a line passing longitudinally through the center of said tube will pass transversely through said axisthat is, the entire tube, except said curved middle part, occupies the same position that it would occupy if it passed through the axis or shaft. 'Each tube is perfectly straight from end to end, except this slight middle curvature, and each end is extended into one of the liquid receptacles, balls, or bulbs D, and through the center of the same nearly to the opposite side. The bulbs are firmly attached to their respective tubes and hermetically sealed after withdrawing the air from each tube and its bulbs, and partly filling the same with ammonia or other easilyvaporizable liquid. A bracing-ring, E, may be attached to the tubes midway between the center of the set, whichlatter, as a whole, is wheel-shaped.

F designates a tank or other reservoir for hot water, which has in its lower portion a separate compartment, F, for lamps or other calorific devices Gr, whereby the water' in said tank is kept constantly heated. This tank is supported by means of chains H, which pass over pulleys h on the tops of standards I, said chains being provided at their outer ends with Weights J, which should be of sufficient gravity to hold said tank at any point to which it may be adjusted. This tank is arranged below the rotating tubes and bulbs, so that the latter will dip into the water during the lower part of their revolution, the extent and duration of such submergence being regulated by the chains and weights, as above mentioned. Of course, any of the known adjusting devices-such as toggles, nuts, and screw-thread ed rods or other equivalents-may be substituted therefor. The water or other suitable liquid in said tank receives and in a measure stores up the heat of the calorific devices above mentioned, and applies the same to all parts of each bulb without any sudden diminution due to a change of draft or exhaustion of fuel. It may even be used for some time after the lamps have been suffered to go out. The bulbs will not be smoked and discolored by it, nor will the danger of injury to them be as great as when flame is directly applied.

, With an equal amount of fuel much greater results will be accomplished, as comparatively little heat will escape without rendering service. As the bulb enters the water the weight of the liquid within said bulb of course facilitates its descent, and after passing the center or lowest point of its revolution the vacuum caused by the action of the heat facilitates its rising, the.bulb then being very light. The extension of the tubes nearly through the bulbs insures the efficient discharge of the entire contents from one to the other. As the tubes are straight and the bulbs centrally arranged on their ends, we avoid the double adverse leverage which has to be overcome when the ends of each tube are bent in opposite directions and attached to the sides of their respective bulbs. With this improved construction the discharge and transfer will be complete almost immediately after the tube passes from avertical position, so the preponderating bulb will have the advantage of all the internal liquid for a greater part of its revolution than'with the other construction, while the other bulb, instead of partly counterbalancin g it at the start by a weight of retained fluid,

will, by its vacuum,be made so light as to offer little or no opposition.

As shown in Fig. 8,we sometimes substitute for the bulbs a series of compartments, K,which are united to form the rim of a wheel or drum, each opposite pair of compartments being provided, preferably, with more than one tube, in order that the flow from compartment tocompartment may be as speedy as possible. Instead of these compartments, we also sometimes use a number of cylindrical receptacles, L, Fig. 4, attached to the outside of the shell or broad tire M of a drum or wheel, each opposite pair of cylinders or receptacles L being supplied by pipes, or in any other convenient manner, instead of heating the water in a tank, as above described. As already indicated, other fluids may be substituted for the water thus used, and various changes may be made inthe construction, combination, and arrangement of the various parts of the mechanism without departing from the spirit and scope of our invention.

Having thus fully described the said invention,what we claim as new, and desire to secure by Letters Patent, is-

1. In a motor, a straight tube having a receptacle at each end and allowing the passage of inclosed volatile liquid from one receptacle to the other under the action of heat, substan tially as set forth.

2. In a motor, a straight tube having each end extended into and nearly through a re ceptacle, and allowing the passage of inclosed volatile liquid from one receptacle to the other under the influence of heat, substantially as set forth.

3. The combination of a series of straight tubes, each having a centrally-attached bulb or receptacle at each end ,with a common axis, and a source of heat for causing the rotation of the series as a whole, substantially as set forth.

4.. The combination of a series of straight tubes, each having its, ends extended nearly through the receptacles attached thereto,with a common axis, and a source of heat for causing the rotation of the series as a whole, substantially as set forth.

5. The method of operating a motor composed of tubes and exhausted terminal bulbs or receptacles partly filled with volatile liquid, consisting in causing each bulb or receptacle to dip into heated liquid during a part of its revolution, substantially as and for the pur= poses set forth.

6. A motor consisting of tubes and terminal receptacles, with inclosed liquid shifting in cacao, in combination with a tank or receptacle containing heated water or other liquid into which the terminal receptacles of the tubes dip, substantially as and for the purpose set forth.
